Tomavistas system and projection, which uses a retrodifusoras divided into regions and alternating-transparent screen on a temporary basis.

摘要

Installing tomavistas for a system of interpersonal communication, comprising a screen (ECR) dividing the space into two half-spaces (SP1, SP2), an observation zone (ZO), a camera (CAM), a first spatial path ( TS1) for a first luminous flux (FL1) propagating at least from the (ECR) screen to the observation zone (ZO) and can receive, in the observation zone (ZO), pictures originating from the screen (ECR ), and a second spatial path (TS2) for a second luminous flux (FL2) propagating at least from the observation zone (ZO) to the camera (CAM), and allowing to form an image of the observation area ( ZO) by means of a sensor (CAP) of the camera (CAM) located in an active state, passing at least partially the first and second luminous fluxes (FL1, FL2) by a common surface (K) of the space being located observation zone (ZO) in the first half-space (SP1), the camera (CAM) being located in the second half-space (SP2), and the said common surface (K) divided on a time basis between the first and second luminous fluxes (FL1, FL2), characterized in that it comprises a projector (PRJ) located in the first half-space being ( SP1) and emitting a third luminous flux (FL3) towards the (ECR) screen, because the (ECR) screen is divided into first and second fractions surface (ECR1, ECR2) complementary to each other and respectively assigned to the backscattering of the third luminous flux (FL3) and for transmitting the second luminous flux (FL2), in that the first luminous flux (FL1) is formed by diffusion of the third luminous flux (FL3) on the first surface fraction (ECR1) of (NCS) screen, because the camera (CAM) is arranged outside the spatial propagation path (SP3) of the third luminous flux (FL3) through the second surface fraction (ECR2), and in that each of the first and Segu nda surface fractions (ECR1, ECR2) is modified over time such that each portion of the screen is alternately transparent and retrodifusora.
